1 <br /> ' exceeds 30 percent for groundwater, data will be qualified as described in the <br /> applicable validation procedure. The RPD will be calculated as follows: <br /> ' jX2 - Xij <br /> RPD = 100 X <br /> ' X2 + Xi <br /> 2 <br /> ' where: <br /> Xi and X2 are the two observed values <br /> One duplicate pair was collected during each day of the sampling event: DUP-01 and <br /> MW-07 for June 1, and DUP-01 and MW-08 on June 23, 2006. DUP-01 and MW-07 <br /> ' were analyzed for diesel-range hydrocarbons, motor oil-range hydrocarbons, VOCs, <br /> and SVOCs. DUP-01 and MW-8 were analyzed for diesel-range hydrocarbons, motor <br /> oil-range hydrocarbons, and metals. <br /> Based on the analytical results, the listed analytical results between the duplicate and <br /> primary samples were out of compliance and were qualified as estimated <br /> concentrations. <br /> Table B-1 <br /> ' Qualified Results for Groundwater Samples <br /> F Analyte Primary Duplicate Units RPD <br /> Result Result Diesel-range 150 110 µg/l31% <br /> hydrocarbons <br /> Diesel-range 1,100 650 pg/l 51% <br /> h drocarbons <br /> ' Motor oil-range 490 <280 /2g/1 55% <br /> hydrocarbons <br /> Matrix Spike/Matrix Spike Duplicate Samples <br /> ' The MS and MSD SPR values for all EPA method analyses were all within the <br /> laboratory control limits for metals, VOCs, SVOCs, and petroleum hydrocarbon <br /> methods. <br /> ' Laboratory Control Sample Spikes <br /> LCS/LCSDs were analyzed for method 8260B, 8015, 8270C, and metals.
